Chapter 8. Advanced JUNOS Services

We discussed the framework for JUNOS services in Chapter 7. This chapter will dive into more advanced scenarios and configurations. Often, you will need to use many Layer 3 services simultaneously, such as Network Address Translation (NAT), stateful firewall, and IPSec virtual private networks (VPNs), so you must plan properly to create transparent service additions.

The topics we will cover in this chapter include:

  • Route tables and next hop service sets

  • IPSec VPNs

  • NAT

  • Combined Layer 3 services

  • Packet flow

This chapter assumes that the reader grasps the concepts discussed in the preceding chapter; specifically, the types of service sets and command-line interface (CLI) configurations. If these concepts are unfamiliar, please review the preceding chapter.
